" mn'rnzon or r'nonucmo Be itknown tha I, MEILICH MELAMIQ, a subject of the Czar of Russia, and residing at Freiburg, in the Grand Duchy of Baden, German Empire,- have invented a certain new and useful Method of Producing Pure Tar Distillates, of which the following is a specification, this application being a d1y1-- sion in part of copending application Senal No. 772,839, filed June 10, 1913, this latter application being a divisional application of my application for Letters Patent Serial No. 732,141, filed November 18, 1912.

In said former application, Serial No. 772,839, division of 7 32,141, I have described a process of treatin tar with phosphorlc acid. "The roducts o tained by this process are ready oruse'without being first subjected to a refining or purification process.

this way that another oxygen compound of phosphorus, ifor instance pyro-phosphoric acid, {meta-phosphoric acid, phosphorus pen'toxid- ,(P O,); orphosphorous acid, or a mixture of'phospho'ric acid with the named other phosphorus-oxygen compounds or a urn-of suchfcompounds in any desired aportionsis made use of.
